The mirror is a grass-leaf four-mountain bronze mirror, round, three-string button, double square button seat, feather-like pattern as ground pattern, reflecting the main pattern of the Chinese character and the petal pattern and leaf pattern arranged between the Chinese characters. The bottom edge of the mountain character is parallel to the side of the square button seat, extending petals from the four corners of the button seat. Each petal connects with a round pistil. The top of the pistil extends a curved long leaf pattern. On the left rib of the mountain character, a round pistil is opposite to the long leaf pattern. The petals and pistils are spun by ropes, totally four petals, eight pistils and four long leaves. The edge of the mirror is narrow, curled and plain. Mirror decoration seems to follow one's will and come with one's own hands, but the arrangement is self-regulated, showing a clear primary and secondary, zero but not chaotic, very vivid. Characteristic mirror is an important type of Chu State Mirror. Its pattern is clear and clear, and it is the representative of the four mountain mirrors.
